bug in docker compose plugin example

[nhooyr]

https://buildkite.com/docs/pipelines/plugins#using-a-plugin

steps:
  # Prebuild the app image, upload it to a registry for later steps
  - label: ":docker: Build"
    plugins:
      - docker-compose#v1.0.0:
          build: app
          image-repository: index.docker.io/org/repo

  - wait

  # Use the app image built above to run concurrent tests
  - label: ":docker: Test %n"
    command: test.sh
    parallelism: 25
    plugins:
      - docker-compose#v1.0.0:
          run: app

I believe that last run step needs a image-repository field as well.

It shouldn't, that information is passed via meta-data.

Ah neat.

Probably deserves at least a comment in the example.

I tried adding it, but I think it just pollutes the clarity of the example, which is meant to just show the syntax for using a plugin twice in a pipeline. Thanks for the feedback though, it was a good suggestion!
